Provided you have a relatively modern version of docker installed, you may brace yourself against the overwhelming senselessness of fear and run `./docker-compile.sh examples/hell_world.spooky` to test out an example (the first time will run a bit slow due to building the docker image and the aforementioned OCaml-building amateurism - over 200 compiler warnings, sorry Jane Street!).
